摘要: 1. Spontaneous activity of male gerbils, Meriones unguiculatus, kept in actographs was recorded continuously from May 1, 1968, through March 15, 1969, Evanston, Illinois. Gerbil studied under two lighting conditions: constant illumination (LL) and 12-12 LD.2. For those gerbils LD a lunar-day periodism spontaneous disclosed for each three seasons (summer, fall, winter). The mean three-season cycle exhibited maxima around times rising setting the moon minima at lunar lower upper transits.3. 5 animals LL reported animal over period averaging 179 days. When cycles were averaged together, with form phase relationship very similar to that found. range this 16%.4. All had locked appr...
